nuke cygwin legacy?

[Christopher Faylor]

Corinna +1'ed my suggestion that it was time to remove cygwin 1.5
support so I'm wondering if anyone has any objections to removing
1.5 from cygwin.com.

I was going to suggest this a few months ago and mention that the Cygwin
Time Machine was an alternative but it looks like that service is no
longer available.

So, as an alternative, we could advertise that the directory is going
away on the main web page for a month before nuking it.
